Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.
Which of the following is an assumption on which the argument depends?
(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.
(B) In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
(C) Equipping a radio station with RDS technology does not decrease the station's listening area.
(D) In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.
(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.
答案A可以理解
但D不选是因为题目已经有说没有装就收不到 违反题意??
如果把D否定
那些没有装机台的could receive 那收的到讯号的人不就增加了
那不就否定了题目了吗?
没有装的跑去隔壁有装的人家收听
不也就增加了吗?
嗯，D只是重述了题目已经给的信息，不管是1994年，还是1996年，收不到就是收不到；后面的推论是你自己加的吧，呵呵，谁说没有装的人家就一定有个装了的邻居？当然，我理解你可能只不过是随便举个例子，但是D其实错就错在没有给出什么有用的新信息。
CR真的好難喔
您所謂新訊息就是不能和題目已經提過的重複?
假設題當中 除了找出gap之外 不就是要想辦法strengthen題意嗎
如果現在選項是把題目已經給出的訊息換句話說
沒有給出新訊息 不是就也不能選呢?
